To all whom it may concern:

Be it known that l, ALFRED C. ABRAMsoN, a citizen of the United States, residing at Rockford, in the county of Wmnehago and State of Illinois, have invented certain new and useful Improvements in Lamps, of which the following is a speclficatlon.

Ihis invention relates in general to the manufacture of electrically equipped devices, such for instance, as electrlc lamps embodying a base and a pedestal, and has more particular reference to the constructlon of such parts in connection wlth the problem of wiring the lamps.

In the manufacture and distribution of electric lamps, especially floor lamps, it is desirable to ship them from the factory to the dealer or user in as nearlycompleted and assembled condition as possible, especially with regard to the electric W1I'1I1g. If lamps comprising a base and pedestal as heretofore manufactured are shipped in separated or knocked-down condition, the dealer, generally unfamiliar with electrlcal work, n 1ust employ an electrician to complete the w ring. On the other hand if the lamps are shipped complete and ready for use each must be carefully and separately crated, which entails considerable time and expense in the packing and a comparatively large cost for shipping, because of the bulky size of the crates.

The primary object of my invention, therefore, is to overcome these ob ect1onable features by the provision of a lamp wh ch may be shipped in knocked-down condltion and yet be completely wired so that pedestals and bases may be completely arranged and crated, thereby reducing to a minimum the cost of crating and shipping, and also so that the dealer or consignee may qu ckly and easily assemble the lamp in condition for immediate use, since the wiring is complete and requires no attention.

In furtherance of this general object I have provided means for detachably securing together a pedestal and a base member 1n an improved manner and have equlpped the pedestal with the proper electric wirmg mcluding a plug connection at the supply end and have also designed the base so that the supply wire may be passed therethrough above the floor line all of which will be more fully described hereinafter. Another object of my invention vlde in connection with the above improve ments, a base and pedestal of the character described so improved in construction as to be capable of being manufactured at a comparatively low cost.

Other objects and attendant advantages Will be appreciated by those skilled in the art as the invention becomes better understood by reference to the following descriptlon when considered in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a pedestal and base of a floor lamp, equipped with electric wiring and embodying my improvements, the base and foot of the pedestal being shown in section;

Fig. 2 is a side elevation of the pedestal detached from the base;

Fig. 3 is a sectional view through the base, detached;

4 is a plan view of the base; and

Fig. 5 is a fragmentary sectional view showin a, modified form of connection between t e base and pedestal.

y improvements are embodied in an electrically equipped device, such for example as a floor lamp of a well known type comprising a base and a pedestal mounted thereon and equipped at its upper end with a cluster of electric lamps and with a shade. It is believed that my invention will be better appreciated if a brief statement is given of the manner in which the lamps of this general character have been previously made. It has been customary to pass the electric Wires for the lamps longitudinally through the pedestal to the underside of the base and to pass the lower or supply end of the wires upwardly through the base at a point outside of the peripheral edge of the foot of the pedestal and to provide this supply end of the wires with a suitable plug connection for attachment with an electric socket. As a consequence ofthis construe tion it was necessary to attach the plug connection to the supply end of the wires after the lamp was fully assembled, hence it was necessary to either manufacture and shi the lamps complete and ready for use or if is to prohit sent in knock-down condition to complete the wiring after the dealer had assembled the lamps, both methods being unsatisfactory for reasons explained above,

Referring now to Figs, 1 to at inclusive, a

base designated enerally by reference character 6 is-provi ed with a central aperture 7 which receives a tenon 8 of a pedestal des' ignated generally by character 9. The ped- 10 estal carries at its upper end a cluster of electric lamp sockets 11 and is adapted to support a shade overlying the lamps, the shade being not shown slnce it has no connection with the present invention. The electric wires for t e lamp sockets 11 pass longitudinally through the pedestal, 1n some instances through a small pipe and in others simply through a hole bored through the pedestal. In the form shown in F g. 1 a small pipe 12 passes longitudinally through the pedestal and projects below the tenon or lower end thereof. The pipe 12 1s fixedly secured to the pedestal and its lower end is exteriorly threaded and receives a nut memher such as a wing or thumb nut 13. With a suitable washer 14 mounted on the pipe 12 intermediate the base and thumb nut, the latter may be tightened so as to rigidly secure the base to the pedestal. The supply end of the electric wiring 15 which enters the pedestal, or more specifically the pipe 12, at its lower end is equipped with a plug connection 16 for attachment with the ordinary supply socket.

My invention designs to so shape the base as to allow a pedestal completely wired, including a plug connection, to be attached to a base with the wiring passing through the base above the floor line without marring the design of either the base or pedestal and allowing the same to be assembled without interference with the electric wiring. In the present instance the wiring passes through an opening 17 in the base at a point just beyond the peripheral edge of the foot of the pedestal, a suitable ferrule 18 beln inserted -in the opening 17 to lend a finishe appearance to the top of the base. The openings 7 and 17 in the base are joined by a slot 19 which enables the completely wired pedestal and base to be attached together for the urpose previously mentioned. This wil be plainly evident by viewing Figs. 2 and 3, showing respectively the pedestal and the base in the condition in which they are shipped from the factory. It will be seen that the wiring is complete and mounted on the wiring is the nut member 13, washer 14, ferrule 18 and connection plug 16. hassembling the pedestal and base, the parts 13 and 14, together with the portion of the wiring 15 adjacent to the pedestal are passed downwardly through the openings 7 and 19 and the tenon is inserted into the opening 7. The washer 14 is then slid up into position and the thumb nut 13 is screwed onto the lower end of the pipe 12 and tightened until the base and pedestal are rigidly secured together. The ferrule 18 is theninserted in the opening 17 and the wiring drawn taut as shown in Fig. 1. It is manifest, therefore, that by constructing the pedestal and base to be detachably connected together and by wiring the pedestal complete and constructin the base so that the parts may be attache together with the wiring passing through the base above the floor line and at the outer side of the pedestal, the objects prefaced above in regard to shipping and assembling lamps of this general character are attained.

My improvements also include an improved base structure designed to accommodate the fastening means between the base and pedestal and to allow a most simple construction so that the base may be produced at a minimum cost. For this purpose the major body of the base is formed of a comparatively fiat piece turned or otherwise formed to the proper design or shape harmonizing with the pedestal. Instead of making this base piece of built up sectional form so as to give proper thickness and prevent warping I have formed it of a single piece, preferably of wood, and have secured to its periphery or marginal portion a metal band 21 projecting below the base such distance as to allow sufficient clearance for the fastening means or nut member 13 above the floor line. This metallic band not only enables the base to be constructed cheaper than the all wood sectional bases but prevents warping and insures against an unsteady, wabbly support.

In Fig. 5 I have shown a modified form of attachment between the base and pedestal. In this, the pipe 12 is omitted and the wiring simply passes through a small bore 22 longitudlnally through the pedestal. The base may be constructed similar to the base first .described. The wiring may also be similar to that first described with the exception just mentioned that the pipe 12 is omitted. The threaded member, however, with which the nut member cooperates to secure the base to the pedestal is secured directly to the tenon of the pedestal. It consists of'a threaded tubular nipple 23 rigidly secured to a cap 24 in turn rigidly secured to the tenon 25 of the pedestal and fitted snugly in the opening 7 of the base so as to properly center the pedestal thereon. The electric wires pass through the nipple 23. It will be evident that this construction allows the pedestal and base to be attached together and detached similarly to the connection of the first described form.

It is believed that the foregoing conveys a clear understanding of my improvements, and it should be understood that while I and base aaaaaea have shown several embodiments thereof, the details of construction might be modified and changed without departing from the spirit and scope of the invention as expressed in the appended claims.
